Heading G1N. The level of material in a container is measured by a probe which forms a cpacitance C2 with the walls and contents of a container and is series connected with a fixed capacitor C1 across the high impedance winding of an impedance transformer, to the primary of which an oscillator is connected. The A.C. voltage V2 developed across capacitor C2 and which fluctuates with the level of material, is rectified and connected to an indicating instrument not shown through an isolating resistance R. All the components shown are accommodated in the sealed head of the measuring probe. The oscillator (not shown) has a low output impedance so that the distance between it and the transformer does not affect the accuracy of measurement and the interconnection of these two components and that between the capacitor of C2 and the indicating instrument may be effected by low grade cables.

Filed: 1919-10-28
Abstract: 158,318. Constantaras, A., and Frydas, J. Oct. 28, 1919. Pneumatically-operated fastenings.-A door is unlatched from a distance by means such as a pneumatic device which releases a catch and allows a tensioned spring connected at one end to the door frame or other fixed part, to pull back the door latch and unlock and partly open the door. When the door is in the closed position, a catch 10 prevents the tensioned spring 7 from withdrawing the door latch through a slidable rod 4 and chain connections 6. The end 9 of the spring is connected to the door frame. By the admission of air pressure through a flexible tube 16 to an expansible casing 15, the pivoted catch member 12 is lifted to release the rod 4. The spring then withdraws the latch to unlock and partly open the door. As the entering person pushes the door open, the spring is relaxed and the rod 4 is drawn back by the spring of the door latch until re-engaged by the catch 10. The device is thus re-set for a further opening movement.

Abstract: 831,903. Centrifugal pumps. SIEMEN & HINSCH. Aug. 26, 1957 [Sept. 24, 1956], No. 26789/57. Class 110 (1). In a self-priming centrifugal pump mounted in a liquid container above the liquid level, the pump casing has at least one bearing bush serving also as a throttle for reducing leakage and disposed so that the leakage passes directly back to the container. The vertical pump shown is suspended within a container 1 by means of a flange 2. The pump, which is of circumferential flow-type and may have a single stage instead of the three stages shown, is rendered self-priming by the provision of a suction chamber 3 in which liquid is trapped when the pump is stopped. The upper bearing 10 acts as a throttling restriction to reduce leakage along the shaft. Leakage is returned to the container 1 through a hole 11 and the acid being pumped therefore does not reach a stuffing box 12, which only has to prevent leakage of vapour.
